Definitions

  • the invention relates to ophthalmic lenses intended to be mounted in eyeglasses frames.
  • the invention relates to a method of manufacturing an ophthalmic lens, to a process of inspecting an ophthalmic lens manufactured thanks to this method, and to an ophthalmic lens manufactured thanks to this method.
  • Preparing an ophthalmic lens for mounting in an eyeglasses frame selected by a wearer comprises five main operations, which are the following:
  • QR code stores in digital form information useful for machining the lens along an outline that corresponds to the one of the frame.
  • this QR code is printed on a sticker that is stuck onto the lens.
  • lenses are generally coated before being edged, for instance to have an anti-reflective film.
  • a risk is that the marks are covered by the coating so that they loose the intended function.
  • one object of the invention is to provide a solution less expensive to apply marks onto lenses.
  • said surfacing instruction is calculated so that said optical face of the ophthalmic lens once surfaced includes a mark that results from said step of surfacing and that forms a code associated with said information.
  • the marking of the lens is done during the surfacing operation, so that it does not require any additional tool, thereby reducing costs.
  • This solution also reduces the complexity of the operation, and do not need any additional time to be performed.
  • the mark can be invisible to the user, so that it can be positioned inside the outline of the lens once edged, that is to say in a part of the semi-finished lens that will not be removed during the edging operation. Consequently, this mark can also be used after the manufacturing of the eyeglasses, to serve for instance as a kind of warranty.
  • the invention also relates to a method of controlling an ophthalmic lens manufactured thanks to a method of manufacturing as specified hereabove, comprising steps of:
  • this method comprises a step c) of authenticating the ophthalmic lens as a function of the decoded information.
  • the invention also relates to an ophthalmic lens comprising two optical faces and suitable to be mounted into a frame in order to be worn by a future wearer, wherein at least one of said two optical faces includes a mark that forms a code associated with an information relative to the ophthalmic lens and/or to said future wearer and/or to said frame and that results from an operation of surfacing the entire said optical face of the ophthalmic lens.
  • FIG. 1 is a view of an image of a surfaced lens, acquired by a photo sensor
  • FIG. 2 is a detailed view of area II of FIG. 1 ,
  • FIG. 3 is a view homologous of the one represented on FIG. 3 .
  • FIG. 4 is a correspondence table between the Alphabet code and the Braille Code.
  • the invention principally relates to a method of manufacturing an ophthalmic lens in such a manner that this lens fulfils an optical function for correcting an optical deficiency of a patient, the latter being the future wearer of an eyeglasses comprising a frame and said ophthalmic lens.
  • this method of manufacturing comprises a first operation of acquiring the optical prescription F 1 of the future wearer, said optical prescription being provided by the wearer's optometrist.
  • This semi-finished lens has a standard shape so that it does not present the desired optical power deduced from said optical prescription F 1 .
  • a third operation consists in machining at least one of the optical faces of the semi-finished lens with machining tools so that the latter presents an optical power equal to the desired optical power.
  • This operation is called “surfacing operation”.
  • the surfaced lens 10 comprises two optical faces 11 , 12 and an edge 13 having a circular outline C 1 around a main axis A 1 (see FIG. 1 ).
  • a fourth operation is to machine the edge of the lens so that the edged lens has an outline C 2 that matches the shape of the corresponding frame rim.
  • This operation consists in acquiring the shape of the frame rim outline, positioning this outline C 2 in the frame of reference of the lens, and cutting out the lens along this outline C 2 .
  • the edged lens and the frame are assembled to form a pair of eyeglasses.
  • the instant invention principally relates to the third operation.
  • This operation can be operated by means of a digitally controlled free-form surfacing machine, the expression “digitally controlled” designating all of the hardware and software acting to provide movement instructions to all the components of the surfacing machine.
  • Such a machine generally includes a spindle bearing a surfacing tool, a support holding the semi-finished lens, a calculating and control-command unit (called herein after “calculating unit”) provided with a data-processing system comprising a microprocessor equipped with a memory allowing it to load and store a software package (also called a computer program) that, when it is executed in the microprocessor, allows the manufacturing method to be implemented.
  • a data-processing system comprising a microprocessor equipped with a memory allowing it to load and store a software package (also called a computer program) that, when it is executed in the microprocessor, allows the manufacturing method to be implemented.
  • the manufacturing method comprises not only the acquisition of the optical prescription F 1 for the future wearer of the ophthalmic lens but also the acquisition of an information F 2 .
  • This information F 2 relates to the ophthalmic lens and/or to the future wearer and/or to the frame.
  • the aim of this acquisition is to memorize this information F 2 onto the lens, thanks to a mark 20 machined onto the lens during the surfacing operation (i.e. by means of the surfacing tool).
  • This information F 2 can comprise one or several data. For instance, it can comprise one or several of the following data:
  • the information F 2 only comprises a lens serial number.
  • This lens serial number here “00312”, comprises five digits.
  • the calculating unit On the basis of the base curve of the semi-finished lens, the prescription F 1 , and the information F 2 , the calculating unit performs a step of calculating a surfacing instruction F 4 for machining at least one of the optical faces 11 of the ophthalmic lens 10 .
  • this step of calculating comprises three sub-steps.
  • the first sub-step consists in determining an intermediate file F 3 as a function of said optical prescription F 1 , considering the base curve of the semi-finished lens.
  • This intermediate file F 3 is calculated according to a well-known method in such a manner that, if the lens was machined by means of this file, it would present a shape enabling it to perform the optical function for which it is designed.
  • the information F 2 is coded.
  • the information F 2 is coded by using the Braille code.
  • each letter can be coded by means of six points and each digit can be coded by means of four points.
  • each digit is coded in our example with four points distributed to the corners of a square.
  • each point can be mathematically represented by a coefficient “1” of a 2-2 matrix (the absence of point being represented by a null coefficient).
  • the calculating unit generates five 2-2 matrixes and deduced therefrom an image as shown in FIG. 3 , comprising five assemblies 21 - 25 of one or two or three or four points, each associated to one of said 2-2 matrixes.
  • the third sub-step consists in determining the surfacing instruction F 4 as a function of the intermediate file F 3 and of the coded information. More specifically, the said image is incrusted into the intermediate file F 3 so that, once surfaced, the lens includes the mark 20 .
  • the surfacing instruction F 4 is calculated so that said optical face 11 of the ophthalmic lens 10 , once surfaced, includes a mark 20 that results from said step of surfacing and that forms a code associated with said information F 2 .
  • the last step consists in surfacing the optical face 11 of the ophthalmic lens 10 according to this surfacing instruction F 4 .
  • the surfacing instruction F 4 is feed into the surfacing machine and the front face 11 of the lens is machined according to this instruction F 4 .
  • the mark 20 is shaped on the front face 11 of the lens, at the same time as the remainder of the front face 11 , thanks to the same tool.
  • the mark 20 is of course machined on this rear face.
  • the mark 20 can be machined on either face of the lens, or on both faces.
  • the mark 20 can be of any shaped, at the condition that the embedded code can be decoded with a decoding device.
  • the mark 20 comprises an array of discontinuous areas, the forms of which and/or the positions of which forming said code.
  • Each discontinuous area presents, along its outline, a discontinuity in terms of heights of points of the front face 11 (the heights being measured along the main axis A 1 ): when observing a section of the front face in a plane that comprises the main axis A 1 and that passes by the center of one of the discontinuous area, the representative curve of the front face 11 in this plane presents an angular point on each side of the discontinuous area.
  • a discontinuous area can be defined as an area bordered by an edge (here circular) or as an area at the contour of which the optical power of the lens varies in a discontinuous manner.
  • each discontinuous area is formed by a micro-lens 21 A- 25 A.
  • Each micro-lens 21 A- 25 A has a circular outline but in a variant, this outline may be in square, oval or other shapes.
  • Each micro-lens 21 A- 25 A comprises an optical power that is different from the optical power of the annular zone of the front face 11 that surrounds it (which generates the discontinuity).
  • the power of the micro-lens needs to be sufficiently small so that the difference in optical power with the annular zone is not noticeable to the future wearer when wearing the lens, yet at the same time, the difference has to be large enough to be detectable by the decoding device.
  • the difference between the optical power of each micro-lens and the optical power of the corresponding annular zone is preferably higher, in absolute value, than 1.5 diopter. In a variant, if the apparatus for decoding the mark 20 is able to perform very accurate measures, a difference fewer than 1.5 diopter can be used.
  • the mark 20 may comprise an array of continuous areas, the forms of which and/or the positions of which forming said code.
  • a zone of the front face 11 of the lens comprises variations of optical powers that are continuous. These variations are greater than in the remainder of the lens.
  • the optical power presents high levels and low levels.
  • the high levels can correspond to the black squares of a QR code (or to the lines of a bar code) and the low levels can be associated to the white squares of the QR code.
  • the levels are distant from each other of 0.1 mm.
  • the array of continuous areas stores the information F 2 in digital form in the sense in that this QR code is associated to a binary code that can be used to memorize the information F 2 , or to an identifier associated to this information.
  • the QR code can memorize the address of a database record in which the information F 2 is memorized.
  • the mark 20 is positioned inside the outline C 2 .
  • the mark 20 remains on the lens 10 after the edging operation, so that the information F 2 remains accessible not only for the edging operation, but also for the mounting of the lens into the frame rim and for after-sale.
  • the mark 20 is positioned in an upper part of the lens.
  • This geometric center (also called “boxing center”) is defined here as the center of the horizontal rectangle in which the outline C 2 is circumscribed.
  • the ophthalmic lens 10 includes a mark 20 that forms a code associated with the information F 2 and that results from the operation of surfacing the entire front face 11 .
  • the mark 20 is not visible by the wearer when the latter wears his eyeglasses. But this mark 20 has to be visible for a user (for instance the optician) who wants to obtain the information F 2 .
  • the user can use either a specific optical device or a nonspecific device fitted with a photo sensor.
  • a specific optical device can be, for instance, a preparation apparatus as disclosed in document US2010228375. Indeed, this apparatus includes a photo sensor and an image processing unit suitable to detect the mark 20 .
  • a nonspecific device can be a mobile telecommunication apparatus, for instance a portable desktop, a mobile phone or a tablet, that comprises a photo sensor and an image processing unit.
  • the image processing unit has to be programmed so as to be adapted to decode the information F 2 .
  • the image processing unit must be programmed to perform a method of controlling the ophthalmic lens 10 , by implementing a first step of acquiring (by means of the photo sensor) a raw image Img 1 of at least a portion of said ophthalmic lens 10 showing said mark 20 (see FIG. 1 ), and a second step of processing this raw image Img 1 in order to decode the information F 2 associated to the Braille code formed by said mark 20 .
  • the second step comprises sub-steps consisting in:
  • the information F 2 once decoded, can be used in various ways.
  • the information F 2 comprises the shape of the outline C 2
  • this information can be used for the edging process, in order to cut-out the surfaced lens along this outline C 2 .
  • the information F 2 can be used during a third step of authenticating the ophthalmic lens 10 in an after-sales service.
  • the user can verify that the lenses of an eyeglasses are authentic, by scanning with a mobile phone the mark 20 and by sending the information F 2 read to a central server that will send him in response a message informing him whether the lens is authentic or not.
  • the encoded serial number serves as a warranty number. As such, the wearer does not need to worry about the loss of a warranty card.
  • the mark is done on the semi-finished lens, before edging the lens along a final outline, and preferably before applying any treatment on the lens. Consequently, the mark is done on the monobloc core of the lens.
